The Angular firestore is showing an error stating that the property 'toDate' is not found in the 'Date' type

I am currently working on converting a timestamp object from Firestore to a Date object in TypeScript by utilizing the toDate() method.

import { AngularFirestore } from '@angular/fire/firestore';
...
constructor(private database?: AngularFirestore) {...}
...
const someVariable = a.date.toDate();

While this functionality is operational in development mode, I have encountered a TypeScript compile check error. Additionally, building the prod version (with ng prod) is proving challenging due to this error.

a.date.toDate() ~~~~ src/app/project/some.service.ts:74:36 -
error TS2339: Property 'toDate' does not exist on type 'Date'.

Does anyone have suggestions on how to address this issue?

Answer №1

Converting to a timestamp using the toDate() function is not compatible with Date, String, Number, etc. To resolve this issue, change the data type of your date variable to any.

date: any;

Additionally, it is recommended to use the toDate() function in HTML files. While it may display an error, it can still compile successfully. Changing the type to any will also help clear up any HTML errors.

Answer №2

The error message indicates that according to TypeScript, a.date is already recognized as a Date, not a Timestamp. This means you need to review the type information for the variable a. If TypeScript is identifying its date property as a Date while it should be a Timestamp, that's what needs to be corrected. Alternatively, if a.date is indeed a Date, then there is no need for the toDate function call. However, considering you mentioned that this code was "working in development mode," it strongly implies that a.date is actually a Timestamp.
